This is incorrect. All codes are two digit. The base diagnosis code is 12. Try again, and post the code for help.

I double checked on the http://www.toyota-supra.info/forums/mkiii-supra/9950-tsrm.html , and your correct about the code 12, except it is an 'RPM Signal malfunction'. However, all codes are still two digit. If you believe the problem is the 'Vane Air Flow Circuit', this must be with the air flow meter, which is a vane style meter. Check the connections, and check the meter box itself to make sure the problem is not internal to the sensors in the meter. Next, you'll need to check for continuity in the lines to the ECM.

Cant remember off hand if this light is in that spot, but if it has a pic of a car with little lines coming out the back side of it that means you have a rear light that is out.
